The process of cooking and processing of potatoes
To cook means to heat the water. She should be hot, but bearable for hands. Water is poured into a bottle of 2 liters and top added 2 teaspoons of tar.
The bottle is closed with a lid with holes. They are drilled with a drill of 0.5 mm Is 5 holes in a row. Pour the solution into a spray bottle, as the tar dries his score.
Local anesthesia is sprayed on the potatoes out of the bottle immediately after emergence. You do not need to fill in every Bush, just spray the solution over the plantation to the majority fall on the leaves.
Bugs hate tar, so don’t sit on a potato for oviposition, while not eroding the smell. Repeating the processing from the moment of germination every 10 days, or more often if there was a heavy rain, it can scare away all summer. If you delay, and the beetle will have time to lay eggs, new larvae will remain. Because of their slowness they can’t get out of the bushes. Tar for them unpleasant, but not fatal, so to combat the larvae still have to resort to poisons.
